Cairo Genizah

<p style='text-align: justify;'>Treatise on the calendar by Josiah b. Mevoraḵ al-ʿĀqūlī, which claims that the Jewish calendar repeats itself exactly every 247 years. He describes the course of the fourteen possible types of the Jewish year, including the beginning of months, holidays and fasts. The arrangement of calendrical data suggests that the fragment was written in the end of the 13th century, around 1296/7 CE.</p>
